A truly exceptional opportunity awaits in Belleair's prestigious Willadel subdivision. Situated high and dry on two-thirds of an acre, this magnificent 7,500+ square-foot estate offers 7 bedrooms, 6.5 baths, a 3-car garage, and access to an exclusive private waterfront park featuring a newly remodeled boat basin. The deeded boat slip with a newer dock and 13,000-pound boat lift provide direct access to the Intracoastal Waterway and Gulf. Arriving via the circular driveway, you'll immediately appreciate the timeless Southern-inspired architecture and grand presence of this remarkable residence. A sweeping staircase welcomes guests through the double-door entry, setting the stage for the elegant living spaces beyond. 155 Willadel was designed with both entertaining (this home has hosted a number of prestigious events) and family living in mind. The gourmet kitchen is equipped with double islands, Wolfe, Subzero and Thermador stainless steel appliances, extensive custom cabinetry, and luxury stone countertops. Adjacent to the kitchen, the expansive great room offers soaring 20’ ceilings, a gas fireplace, and a climate-controlled wine room. Also downstairs is a formal dining room with adjoining butler's pantry, a gracious living room with custom built-ins, wood-burning fireplace, hardwood flooring, crown molding, and two sets of French doors that open to a charming front veranda. Four downstairs bedrooms – two en-suite and two sharing a jack and jill bath – provide plenty of comfortable space for family and guests. Upstairs can be accessed by front or back staircases, as well as an elevator, where you will find 3 oversized bedrooms, all of which are en-suite. The primary features a private balcony, two large walk-in closets and a beautiful remodeled primary bath with soaking tub and separate shower. One of the other upstairs bedrooms has a wood-burning fireplace, private balcony, and spacious walk-in closet. Both upstairs balconies have peeks of the intracoastal. Additional amenities include upstairs and downstairs laundry rooms, a private theater room with projector and large screen, a wet bar, game room, and numerous custom built-ins throughout. The flexible floor plan provides abundant space for family, guests, and entertaining. Outdoor living is equally impressive, featuring a covered lanai with a spectacular outdoor kitchen overlooking the spacious, private backyard lined with mature podocarpus. The property’s RE (Estate Residential) zoning classification and large backyard allow for the construction of an additional structure as well as ample room for a resort-style pool. Other recent upgrades include impact-rated windows and doors throughout, a completely replumbed home, updated electrical throughout, and a whole-house generator for added comfort and peace of mind. Located just minutes from Clearwater Beach, fine dining, boutique shopping, and premier golf destinations including Belleair Country Club and Pelican Golf Club, this extraordinary estate presents a rare opportunity to enjoy luxury living in one of Florida's most sought-after boating, golf, and racquet communities.
